Detailed Description

The SoPointSizeElement changes the pointsize setting of the render state.

Requests from the scenegraph to change the pointsize when rendering point primitives will be made through this element.

The SoPointSizeElement class itself is just a generic abstraction for the underlying So*PointSizeElement classes with code specific for each supported immediate mode rendering library.

Constructor & Destructor Documentation

SoPointSizeElement::~SoPointSizeElement ( void  )

protectedvirtual

Destructor.

Member Function Documentation

void * SoPointSizeElement::createInstance ( void  )

static

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

void SoPointSizeElement::init ( SoState *  state )

virtual

This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.

Reimplemented from SoFloatElement.

Reimplemented in SoGLPointSizeElement.

void SoPointSizeElement::set ( SoState *const  state, SoNode *const  node, const float  pointSize  )

static

Static method for setting the current pointSize value in the given traversal state.

void SoPointSizeElement::set ( SoState *const  state, const float  pointSize  )

static

Static method for setting the current pointSize value in the given traversal state.

float SoPointSizeElement::get ( SoState *const  state )

static

Static method for returning the current pointsize setting in the given traversal state.

float SoPointSizeElement::getDefault ( void  )

static

Returns default pointsize setting.
